The information in this article applies to:
 
 - Microsoft PowerPoint for Windows, versions 4.0, 4.0a, 4.0c

SYMPTOMS
========
 
If you play an embedded Video for Windows (AVI) movie before another sound
object has finished playing, the video will be played without its
soundtrack.
 
This problem happens most frequently if you have a long sound object on one
slide that is still playing when you advance to the next slide. A movie on
the following slide will be played without its soundtrack.
 
CAUSE
=====
 
Media Player can't use the Windows sound driver if another application is
also using it. When Media Player plays a movie, it checks to see if the
sound driver is available. If the driver is not available, the movie is
played without audio.
 
WORKAROUND
==========
 
Use the following steps to adjust the play settings for the movie so that
the movie will not start playing until after the sound object finishes:
 
1. Note how long the sound file takes to play.
 
2. Select the movie object and click Play Settings on the Tools menu.
 
3. In the Start Play section of the Play Settings dialog box, select the
   When Transition check box, then select the Ends, Plus option. In the
   text field, type the number of seconds that is larger than the number of
   seconds the sound object will be playing.
 
4. Choose OK.
 
When you run the slide show, PowerPoint will wait the number of seconds you
specified in step 3 before it plays the movie. If the sound object has
finished playing by then, the movie will be played with audio.
 
STATUS
======
 
This is not a problem with PowerPoint. If you play a long sound file using
the Windows Sound Recorder, then try to play a Video for Windows file in
Media Player, the movie will also play without audio.
